How To Test Optocoupler || Opto Isolator / Optocoupler Tester . ILQ5. it is used in voltage. i explained how to test ilq5 4 channel optocoupler. we can make tester in very easy steps. i explained how to design tester for optocoupler. i applied a test signal to input side LED and i tested the output side opto transistor, interfacing board, to couple high voltage signal, controlled by microcontroller signal. Optocoupler, Phototransistor Output (Dual, Quad Channel)
The ILD1, ILD2, ILD5, ILQ1, ILQ2, ILQ5 are optically coupled isolated pairs employing GaAs infrared LEDs and silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the drive while maintaining a high degree of electrical isolation between input and output. The ILD1, ILD2, ILD5, ILQ1, ILQ2, ILQ5 are especially designed for driving medium-speed logic and can be used to eliminate troublesome ground loop and noise problems. Also these couplers can be used to replace relays and transformers in many digital interface applications such as CTR modulation. The ILD1, ILD2, ILD5 has two isolated channels in a single DIP package and the ILQ1, ILQ2, ILQ5 has four isolated channels per package.
